First solution: Reboot your Galaxy A6 2018 (soft reset).
If this is the first time you encounter the No SIM card error on your device, it could be just a random glitch that can easily be dealt with by a device restart or soft reset. Here’s what you should do then:
- Press down on the Power button and hold it down for several seconds until the menu option appears. Then select Restart from the given options.
- Alternatively, you can just press the Power button until the screen goes off and then after about 30 seconds, press the Power button again to turn it back on
A soft reset is the simplest efficient solution to minor issues inflicted by software errors on the phone. This won’t affect any data and personal information saved in the internal memory or your device, therefore you won’t lose anything in the process.
Second solution: Remove and reinstall the SIM card.
Your device might not be able to detect your SIM card and prompts you the No SIM card error because the SIM card is loose or not properly seated. To make sure this isn’t the underlying cause, you can remove and reinstall the SIM card on your Galaxy A6 2018 with these steps:
- Insert the ejection pin (SIM ejector tool) into the tiny hold on the SIM card tray. To prevent causing damage to your device, ensure that the pin is perpendicular to the hole. When you hear a slight click, it means that the tray pops out.
- Gently pull the tray out from the slot.
- Remove the SIM card from the tray then examine for any visible signs of damage.
- If everything looks good, place the SIM card back in the tray with the gold colored contacts facing downwards.
- Insert the SIM card tray back into the SIM card tray slot.
- Push the tray back in to close it. Make sure it is closed tightly to prevent water and dust from entering the device.
Once you’ve got everything back into place and secure, turn your phone on. See if that fixes the error.
Third solution: Reset network settings on your Galaxy A6 2018.
Invalid settings particularly those that are associated with network functions can also trigger similar errors to occur on your phone. This usually happens when new software updates or files are implemented. Some updates automatically override your current settings and eventually results to errors including this. If you’ve setup your device to auto-update, then you may need to reset network settings and manually reconfigure your network options with these steps:
- Open the Apps drawer.
- Tap Settings.
- Tap System.
- Tap Reset Options.
- Select the option to Reset WiFi, Mobile & Bluetooth.
- Tap Reset Settings.
Your phone will restart automatically when the reset is finished. After the restart, you will need to set up your wireless networks to connect your phone to the Internet again.
Fourth solution: Update your Galaxy A6 2018 software to the latest version available.
Software updates also integrate bug fixes or fix patch to address existing issues caused by software bugs and malware on the phone. If you haven’t yet updated your Galaxy A6 2018 software, then you can check for an update with these steps:
- Open the Apps tray.
- Tap Settings.
- Tap Software Update.
- Select the option to Download updates manually.
- Wait for your device to check for updates.
- If an update is available, you will see an update notification. Tap OK then select Start to instigate downloading and installation of the update file.
- When the restart message appears, tap OK to reboot your device and apply the recent software changes.
Restart your phone afterwards to implement the recent changes and to refresh your phone system as well.
Fifth solution: Reset your Galaxy A6 2018 to factory defaults (master reset).
A full system reset or master reset is often needed if the error persists after exhausting all prior means to fix it. It could be a more complex system issue that’s preventing your Galaxy A6 2018 from reading the SIM card. This means the need for a more advanced solution like a master reset. Be sure to note though that this reset wipes everything from your device including your personal information and other critical data saved in the internal memory. Should you wish to continue, back up all your important data beforehand. Then follow these steps whenever you’re all set:
- Tap Settings from the main screen.
- Tap General Management.
- Scroll to and tap Reset.
- Select Factory data reset from the given options.
- Read and review the warning message then tap Reset to continue.
- Tap Delete All to confirm factory data reset.
Alternatively, you can perform a factory data reset through Android recovery menu on your Galaxy A6 2018, using hardware keys. This method is recommended to reset an unresponsive device but can still be carried out if you would prefer to reset your phone that way. Both reset methods will result to data loss.
If your Galaxy A6 2018 smartphone still shows a NO SIM card error after performing all applicable workarounds and possible solutions, then you should already consider opting for service. The SIM card or other relevant hardware components might have been damaged and therefore needed some repair. That being said, take your device to a nearest Samsung service center and have it checked by an authorized technician.
Alternatively, you can contact your device carrier for further assistance and recommendations. Don’t forget to avail for service or replacement warranty if needed.
